Geissele 6mm Suppressor Alignment Gauge

The Geissele suppressor alignment gage (SAG) is a precision instrument designed to verify the alignment of a suppressor with the bore of a firearm barrel. It is crucial to recognize that the suppressor's length typically exceeds that of the barrel, muzzle device and suppressor interface geometry. A minor deviation at the mounting interface can result in a significantly larger misalignment at the suppressor's exit hole. These deviations can accumulate, further exacerbating suppressor misalignment
